<p>Pediatric mechanical circulatory support (MCS) has been successfully used to bridge numerous children to transplantation who otherwise would have been unlikely to survive on the waitlist and, in many cases, make them better transplant candidates. The purpose of this study was to analyze what the pediatric heart failure community has achieved over the last 15 years in reaching 1,200 cases of bridging children to heart transplantation. The United Network for Organ Sharing database was used to identify MCS patients ages 0-18 at the time of listing for heart transplantation between 2005 and 2019, divided into three eras: first (2005-2009), second (2010-2014), and third (2015-2019). From 2005 to 2019, 1,289 pediatric cases were identified. More patients were successfully bridged to transplantation with MCS in the third-era (28%) [vs. first-era (16%), second-era (24%), p ≤ 0.004]. The proportion of discharges on ventricular assist device has increased as well from 3% to 22% (p &lt; 0.001). Post-transplant survival was significantly better in the third era (1-year survival: 96%; 3-year survival: 89%) compared to the two previous eras (p = 0.006). On MCS, renal dysfunction, ventilator dependence, inotrope use, and functional status improved from the time of listing to transplantation (p &lt; 0.01). Hepatic dysfunction (p &lt; 0.001), renal dysfunction (p = 0.004), congenital heart disease (p = 0.023), and infant age (p = 0.002) were risk factors for post-transplant mortality. Over the last 15 years, pediatric MCS has become an accepted and increasingly used strategy for bridging children to transplantation. MCS therapy is associated with improved end-organ function at the time of transplantation, perhaps contributing to the increasing post-transplantation survival of patients bridged with MCS.</p>

<p>Pediatric centers are implanting durable adult continuous-flow ventricular assist devices (CFVADs) in children who are smaller than the industry-recommended size. Waitlist and posttransplant outcomes data in pediatric patients supported with CFVADs as a bridge to transplant are limited. We analyzed the United Network of Organ Sharing and Organ Procurement and Transplantation Network registry to identify patients aged ≤18 years with a CFVAD at the time of listing or transplantation. Patients were stratified by body surface area (BSA; &gt;1.5 vs. ≤1.5 m(2) ) at time of listing. We identified 138 patients with a durable CFVAD during the listing period (100 with BSA &gt;1.5 m(2) , 38 with BSA ≤1.5 m(2) ). Patients with BSA ≤1.5 m(2) were more likely to have a noncardiomyopathy diagnosis (18% vs. 4%, p = 0.007) and to be implanted with a centrifugal-flow rather than an axial-flow device (74% vs. 30%, p = 0.001). There was no difference in failure-free waitlist survival between BSA groups (p = 0.99) among patients with a CFVAD at listing. Posttransplantation survival was 100% and 88% at 1 and 5 years, respectively, for the entire cohort and did not differ by BSA group (p = 0.99). Consequently, waitlist and posttransplant outcomes are favorable for pediatric CFVAD recipients. Small patients (≤1.5 m(2) ) had pre- and posttransplant outcomes similar to those of larger patients that met the industry-recommended size for implantation.</p>

<p>Scarce data exist regarding costs of pediatric heart failure-related hospitalizations (HFRH) or how costs have changed over time. Pediatric HFRH costs, due to advances in management, will have increased significantly over time. A retrospective analysis of Healthcare Cost and Utilization Project Kids' Inpatient Database was performed on all pediatric HFRH. Inflation-adjusted charges are used as a proxy for cost. There were a total of 33,189 HFRH captured from 2000 to 2009. Median charges per HFRH rose from $35,079 in 2000 to $72,087 in 2009 (p &lt; 0.0001). The greatest median charges were incurred in patients on extracorporeal membrane oxygenation ($442,134 vs $53,998) or ventricular assist devices ($462,647 vs $55,151). Comorbidities, including sepsis ($207,511 vs $48,995), renal failure ($180,624 vs $52,812), stroke ($198,260 vs $54,974) and respiratory failure ($146,200 vs $48,797), were associated with greater charges (p &lt; 0.0001). Comorbidities and use of mechanical support increased over time. After adjusting for these factors, later year remained associated with greater median charges per HFRH (p &lt; 0.0001). From 2000 to 2009, there has been an almost twofold increase in pediatric HFRH charges, after adjustment for inflation. Although comorbidities and use of mechanical support account for some of this increase, later year remained independently associated with greater charges. Further study is needed to understand potential factors driving these higher costs over time and to identify more cost-effective therapies in this population.</p>
